Type specimens. HOLOTYPE ♂, 5 km W Hattah-Kulkyne NP, Victoria, 34.762°S 142.292°E, 5 Nov 2013, M. Batley, ex Eremophila deserti , in AM ( K470033 ) . PARATYPES (13♀♀, 8♂♂, all deposited in AM) . Victoria: Hattah-Kulkyne NP, 5 Nov 2013 (K470031–032), 3 Nov 2014 (K470034–052), M. Batley, ex Eremophila deserti .

Diagnosis. Female clypeus black, facial fovea <⅓ length of eye, femora black except apically. Distinguished from E. microdonta by absence of teeth on clypeal margin, from E. deserti by the black femora, from E. kubinensis by black metasoma without prominent translucent tergal margins. Male face yellow to top of fovea, scutum black, lower half mesepisternum yellow, subantennal sulcus relatively long. Distinguished from E. microdonta principally by terminalia.

Description. Female.—Head width 1.01 mm, body length 3.2 mm. Relative measurements: HW 50, HL 46, UID 32, LID 25, FVL 8, CW 21, CL 9, Fl 25. Head black with mandible, labrum, flagellum ventrally yellow-brown; scape and flagellum dorsally dark brown. Ventral margin of clypeus without teeth but outer edge has a slight thickening or small tubercle. Frons dulled with strong tessellation and weak, open punctures. Mesosoma black except pronotal tubercle, spot on tegula and alar sclerites bright yellow; legs yellow except coxae basally, femora (except distal end), distitarsi and medial patch on hind tibia dark brown or black. Scutum dull with small punctures on a strongly tessellate ground, openly punctate becoming close anteriorly. Fore basitarsal setae stiff, capitate; setae on ta2–4 stiff, apically hooked 90°. Metasoma black with transverse lineolation and sparse punctures.

Male.—Head width 0.88 mm, body length 2.7 mm. Relative measurements: HW 50, HL 45, UID 34, LID 26, FVL 10, CW 21, CL 10, FL 35. Head yellow except vertex, occiput, dorsal 20% of gena and frons down to mid-point of fovea black, with narrow yellow line to top of inner orbit. Mandibles with ca 4 stiff but not particularly robust setae. Frons dull with strong tessellation obscuring any punctures. Mesosoma black with following areas yellow: pronotum laterally (including tubercle), anterolateral corners of scutum, tegula, alar sclerites, mesepisternum below subalar pits, ventral ½ metepisternum, legs (becoming yellow-brown distally). Surface sculpture like that of frons. Metasoma black dorsally and yellow ventrally, except T6 and lateral margins of T1–5 yellow, the yellow on T2,3 frequently visible from above. S5 with prominent fringe of white hair, short medially.

Remarks. On a single day, significant numbers of this species and E. fultoni were collected in the same area. Without exception, E. elizabethae was taken at different sites from Eremophila deserti , while E. fultoni was found on Eucalyptus sp.

Etymology. This species is named in memory of Prof. Elizabeth Exley who contributed so much to the study of the Euryglossinae . Many bee species have been named in her honour, but none in this subfamily.
